Postgres: Installing as a service

[CM J <postgres.newbie@xxxxxxxxx>]

Hi ,

       I have extracted postgres from postgres-noinstaller.zip file. How do i install postgres as  a service from cmd line ? Are there are any binaries provided by postgres to install it as a service ? Please note that i am aware that msi installer automatically does all this. I want to know how to acheive the same from  the postgres db extracted from the zip file.

Thanks.
